here are a little (incomplete) list of RFC2460-compliant
implementations that does not speak/understand HAO:
JunOS, ExtremeWare, MacOS 10.2, all FreeBSD since 4.0, all NetBSD
since 1.5, all OpenBSD since 2.7, Solaris beyond 2.7, Linux since 2.2,
all BSD/OS since 4.1.
and any product that ships with these operating systems (note that
many uses *BSD in embedded products such as printers).
and i would like to stress that it isn't matter of configuration, but
matter of codebase (you can't say "well, they are not configured with
IPv6"). and as you may aware, people do run older revisions of those
operating systems (there still are Win3.1, you know).
if it isn't enough to convince you otherwise, i think you are in
a dream world.
